Why it _shouldn't_ be SOAP?
It's a perfectly fine protocol, with a rigid schema and mature code generation support for all relevant languages. It's not the sexiest protocol, but it gets the job done.
And what are the alternatives? JSON schema?

Heh, "relevant languages" is kind of an interesting term there. If the relevant language is Java then sure, it's fine.
Some popular modern languages (ie Go) don't have good SOAP support (yet). At least not to the point of being able to point them at WSDL/XSD specs and have everything auto-generated. :(
It's more than just a few days of effort though. Sme of the members of my team at work have been working on adding SOAP 1.1 support. It's a significant amount of time and effort though.
That's just no how the real world works. When this was launched Go probably wasn't a relevant language, Rust probably barely existed and the whole thing was designed for a corporate setting, where Java and .Net are the standards. All those who are asking "Why SOAP?" or suggests replacing it seems rather naive about how most corporate software is sold, designed, built and maintained, as well as expected lifetimes of solutions.
Yeah, fully agree. I was super surprised to find the SOAP support is practically non-existing too, as Go is really strong in lots of other areas. :(
That being said, SOAP's stronghold is clearly the Java ecosystem. Wonder if it's as popular in any other non-java-ecosystem based languages?
I really think outside of Java and c#, soap is totally dead.
Most places in my experience just write their own wrappers/frameworks to generate what they know works, and go to town. I’ve done it too.
Are you meaning in my comment, or in the GitHub repo the article references?
Asking because AFAIK the theory of having (accurate) vendor provided WSDL/XSD files is that you can generate a bunch of code (ie parsers, strong validation) that works with it, generate tests. There are additionally well developed SOAP specific GUIs (ie www.soapui.org) which will directly load the WSDL/XSD files and let you immediately make test network calls to validate things.
Though sure, you can do the above manually without WSDL/XSD files, but if you have accurate ones provided to you by vendors then it makes things a lot easier.
Which is also my experience too.
Or have you not dealt with decade+ long services with severe inertia/lockin? Because that is what lets them get away with this.
Correct, yes I haven't.
Other members of staff where I'm working are from Java backgrounds, and have described (in detail) WSDL/XSD (when things are accurate) in positive terms as I put above.
And yeah, I'm presently dealing with vendor specs/docs that don't match what's actually sent over the wire, and it's a huge pain in the arse. And the vendor doesn't give a shit, as like you allude to they're in the telco business so the lock in aspect you mention is correct to. :(
ASN.1? It's even more mature, and the de-facto DER/BER encoding is far more efficient to generate and parse than anything XML-based.
